@ toonice - It happened to my new Samsung 860 Evo 1TB 2.5 from PCW**** as well. What happened was, Samsung Magician initially detected the SSD, and then I updated the firmware to the newest version. After I restarted ganyan na lumalabas sa akin. What I did was I restarted the laptop again and naging ok na. Just make sure you're connected to the internet. HTH.
